ASTRO™

AIR SOURCE

Supplied Air

Locate the air source in a clean air environment, always use a ﬁlter on the inlet of your air

source. Make sure the air source is somewhere that vehicles, forklifts, and other machinery

are not running near the air inlet, as this will cause carbon monoxide to be drawn into your

air supply. Always use suitable after coolers/dryers with ﬁlters and carbon monoxide alarms

to ensure clean breathable air is supplied at all times. A Radex® Airline Filter (04-900) and

a GX4® Gas Monitor (08-400) are recommended. The air should be regularly sampled to

ensure that it meets Grade D requirements.

AIR QUALITY

This respirator must be supplied with clean breathable air at all times. Breathable air must at

least meet the requirements for Type 1 gaseous air described in the Compressed Gas Association

Commodity Speciﬁcations G-7.1 (Grade D or higher) and as speciﬁed by Federal Law 42 CFR

84, subpart J.84.141(b) and 29 CFR 1910.134 (i) the RPB ASTRO does not purify air or ﬁlter

contaminants. A carbon monoxide monitor must be used at all times.

Do not connect the respirator’s air supply hose to nitrogen, toxic gases,

inert gases or other non-breathable air sources. Check the air source

before using the respirator. This apparatus is not designed for use with mobile air supply systems

i.e. cylinders. Connecting the supply hose to a non-breathable air source will result in serious

injury or death.

BREATHING AIR SUPPLY HOSES AND FITTINGS

RPB® breathing air supply hoses and ﬁttings must be used between the point of attachment

and the respirator breathing air connection at the wearer’s belt. The hose sections must be

within the correct length and the amount of sections must be within the number speciﬁed in

the breathing air pressure table on pages 13-14.

BREATHING AIR PRESSURE

The air pressure must be continually monitored at the point of attachment. Air pressure must

be read from a reliable pressure gauge whilst the respirator has air ﬂowing through it.

other RPB® products you are using.

MAKE SURE THE SYSTEM IS READY FOR USE

Make sure you have a complete system. Verify that you have all required components for the

ASTRO to serve as a complete NIOSH approved respirator:

 Respirator Helmet Assembly (ASTRO)

 Breathing Tube Assembly

 Flow Control Device (Flow Control Valve or C40™ Climate Control Device)

 Breathing Air Line

See Respirator Component Diagram (page 6). The RPB ASTRO is only approved to be used with

the RPB® Flow Control Valve, RPB C40 Climate Control Device, or RPB Low Pressure Constant

Flow Valve. Use only authentic RPB brand parts and components that are part of the NIOSH

approved respirator assembly. Using incomplete or inappropriate equipment, including the use

of counterfeit or non-RPB parts, can result in inadequate protection and will void the NIOSH

approval of the entire respirator. Do not modify or alter any part of this product.

Inspect all components daily for signs of damage or wear and tear that may reduce the level

of protection originally provided. Remove any damaged component or product, including any

helmet or visor that has been subject to impact, from service until repaired or replaced. Scratched

or damaged safety lenses or other components should be replaced with genuine RPB brand

replacement parts. When safety and impact lenses are replaced, make sure to remove any

additional protective ﬁlm from both sides of the lens. If the ﬁlm is left in place, it could affect the

optical clarity of the lens and cause eye strain. Inspect the inside of the respirator for respirable

dust or other foreign objects. Keep the inside of the respirator clean at all times.

Make sure that the helmet is correctly assembled in the conﬁguration that suits your application.

Never use the respirator without all lenses in place. This includes the Inner and Outer Lenses.

These lenses, when installed properly, are part of the respiratory seal to prevent toxic or

ASTRO™

hazardous gases, liquids or dust from entering the helmet. An incomplete or improperly installed

lens system could provide inadequate impact and respiratory protection. See Respirator Setup

and Care (page 15). See Donning (page 17) for ﬁt information.

VERIFY THAT YOU HAVE THE APPROPRIATE EQUIPMENT FOR YOUR ACTIVITY

Verify that the ASTRO provides appropriate protection for your activity. As applicable, check your

workplace safety program, respiratory protection program, and standards and regulations for your

Make sure you understand the Breathing Air Pressure table before

using this respirator.

1. Select the correct air source (column 1).

2. Conﬁrm the part number of the air supply hose you are using (column 2) and the ﬂow

control device (column 3) you are using.

3. Check your RPB® Safety Air Supply Hose is within the correct length (column 4) and the

correct number of hose sections (column 5).

4. Set the air pressure at the point of attachment within the range speciﬁed (column 6).

Make sure air is ﬂowing through your respirator when setting the air pressure.

Failure to supply the minimum required air pressure at the point of attachment for the length

of air supply hose will decrease the level of protection provided. In addition, could result in

contaminants being inhaled as the pressure in the helmet may become negative due to peak

inhalation ﬂow when working at very high work rates. Low airﬂow will decrease the level of

protection provided.

If the Breathing Air Lines and Flow Control Device have RZ

™ ﬁttings, they will only attach to

other RZ ﬁttings. They will not work with Universal Couplers. Do not modify air line ﬁttings. RZ

ﬁttings prevent connection to unsafe air sources.
